Q: Is Git Status a fully functional Git client?
A: No, Git Status is not a fully functional Git client, it is designed to show the working copy status only. You still need other Git clients to manage your Git repositories.

Q: There is no icon overlay for the files?
A: Please make sure that you’ve enabled “Git Status Extension” in “System Preferences » Extensions”, and also make sure that you’ve added the working copy to Git Status. If the problem persists, please disable “Git Status Extension” in “System Preferences » Extensions” and then enable it again. The last resort is to relaunch Finder or restart your computer.

Q: Does Git Status work well with other Git clients?
A: Yes. In theory, Git Status works with any kinds of Git clients, from the command line to the GUI apps.

Q: Does Git Status work for file managers other than Finder?
A: Git Status is primarily a Finder extension, so it is likely that it will not work for other file managers.
